Definitions

  • the present invention relates to high voltage electrical connectors, such as high voltage circuit breakers, switchgear, and other electrical equipment.
  • Typical dielectric materials used in high voltage applications include air, oil, or sulfur hexafluoride (SF 6 ) gas.
  • Air requires a long distance between contacts in order to reduce the likelihood of arcing in high voltage (e.g., 5+kV) environments.
  • oil requires shorter distances between contacts, but oil is subject to igniting when a fault occurs and may contain harmful polychlorinated biphenyls (PCBs).
  • PCBs polychlorinated biphenyls
  • SF 6 gas requires relatively short distances between contacts, but use of SF 6 gas is undesirable for environmental protection reasons.

  • high voltage at conductive housing 112 e.g., “X” Volts AC, as shown in FIG.
  • silicone gel 132 as a dielectric insulator enables use of a relatively small distance, D ( FIG. 1 ), between conductive pin 204 and bus 106 , when pin assembly 200 is in the open position.
  • distance D may generally be less than three inches and, more particularly, about two inches.

  • the bushing portion and the conductive housing may be joined to axially align the first bore and the second bore and to form an internal chamber (e.g., internal chamber 130 ) around a portion of the pin assembly, such that the internal chamber separates the first bore and the second bore.
  • a gelatinous silicone material e.g., silicone gel 132

  • a high-voltage connector device that includes a device body and a pin assembly.
  • the connector device may include a bushing portion with a conductive bus having a first bore, a conductive housing with a second bore that is axially aligned with the first bore, an internal chamber separating the first bore and the second bore, and a gelatinous silicone material enclosed within the internal chamber.
